Vepr 12
Muzzle brake CSS US version (http://store.carolinashooterssupply.com/servlet/-strse-1577/MOLOT-GK-dsh-01-VEPR-SAIGA/Detail)
Factory Molot mag 5 rds, I used two that came with a gun
Shells - Winchester 2 3/4 1255 velocity 1 1/8 oz 7 1/2 shot
Federal 2 3/4 1145 velocity 1 1/8 oz 8 shot
buck 2 3/4 " 00 wolf, rem 3" 4 bk were fine.
No RDS was used
Same shit with mine, just got it last Friday, I mounted CSS brake right away , hoping and relying on what people say it does not cause any FTE, but I had FTE with 7 1/2 and 8 target loads every other time. Please help!!!
